VENTILATOR.

Application filed May 28,

'lhii application is a continuation in part of my U. S. application Serial No. 249,743, filed January 26th, 1928, and allowed April th, 1928.

The invention relates to improvements in ventilators oi the type to extend across the. lower portion of a window trame to admit fresh air when the lower sash of the window is partly raised. The ventilator is provided with a cover preferably having openings covered with fine screen wire to prevent entrance of dust and the like, and it is the principal object of my invention to provide novel mounting means for this cover, permitting .it to be moved inwardly and downwardly and suspended in a substantially vertical position at the inner side of the ventilator body, when its use is not desired, and permitting said cover to be totally detached whenever desired.

Further objects are to provide a cover of simple and inexpensive, yet strong and durable construction, securing a sheet of woven wire in place in a unique manner, and to also provide the cover with such construction as to readily secure a rubber or other flexible strip thereto, for contact with the lower window sash.

With the foregoing in view, the invention resides in the novel subject matter hereinatter described and claimed, description being accomplished by reference to the accompanying drawing.

Fig. 1 is a horizontal sectional View through a window illustrating a top plan view of the ventilator.

Fig. 2 is an inner side elevation of the parts shown .in Fig. 1.

Fi 3 is a vertical transverse section as indicated by lines 33 of Figs. 1 and 2.

Fig. 4: is a fragmentary end elevation illustrating the manner in which the ventilator cover may be moved inwardly and downwardly and suspended in a substantially vertical position.

Figs. 5 and ('3 are enlarged detail longitudinal sectional views on lines 5 5 and 6-6 respectively, of Fig. 1.

Fig. 7 is a disassembled perspective view of portions of the cover.

In the drawings above briefly described. the numerals 8 denote two substantially tri angular end members preferably formed of metal and adapted to be secured by screws or other means 8 to opposite sides of a window frame, at the inner side of the lower 1928. Serial No. 281,132.

sash S. Extending between the end members 8 is an inwardly inclined inner wall 8" which is preferably formed of glass with its ends held between flanges 8 on said end members, said wall 8 and said end members 8 forming a ventilator body of substantially the same ctmstruetion as those now in com men use.

A cover 9 rests normally upon the wall 8 and the end members 8, said cover embodying upper and lower sheet metal plates 10 and 10 having air inlet openings 11 which are covered with screen Wire 12 held between said plates. The inner edge of the plate 10 turns downwardly as at 13, providing a flange disposed at the inner edge of the cover 9 to engage the wall 8", while the outer edge of said cover is provided with a yieldable strip 1-1. of rubber or other desired material, to engage the sash S.

Between their longitudinal edge portions, spacing means are provided for the plates 10-10, said spacing means being shown in the form of bosses 1t) stamped upwardly from the plate 10 and spot-welded to the plate 10, as at 10. This construction is si1nple and easy to manufacture, yet with light sheet material for the plates 10-10% so connects them as to provide a rigid cover structure. The sheet of screen wire 12 may be inserted between the two plates after they have been welded together as they are held in sufliciently spaced relation to readily permit inward sliding of said sheet.

At their outer longitudinal edges, the plates 1tl10 projectbeyond the wire sheet 12 as indicated at 14* and 14 respectively. The inner portion of the flexible strip 14 is received between the plate portions 14= 14 and is provided with a longitudinal bead 14. This bead is received in a groove 14 formed by stamping the plate portion 14). The bead 14" may be molded upon the strip 14 or may be formed by bending an edge portion of this strip around a wire 14. In either instance, the strip 14 will be tenaciously anchored between the plates 10-10, yet may be removed, should age dictate that a new strip be substituted.

Short metal channel bars 15 receive and are secured by rivets 15 to the ends of the plates 10-40, each of these bars being provided with an upstanding car 16 at its intermediate portion struck outwardly iroi'n its lower flange and its vertical, flange-connecting portion. Two outwardly inclined links 17, disposed at the outer sides of the end members 8, have their upper ends pivoted at 17 to these cars 16, while t'OlllblIlQd pivotal and slidable connections are provided between the lower ends of the links 1.7 and the end mcn'ibers 8.

These connections consist of slots 18 formed in the links 17, and bolts or the like 19 passing loosely through said slots and secured in openings in the end members 8. The slots l8 of the links 17 are formed With lateral throats 15 When the cover is moved to a position permitting vertical disposition of the links. the-e throats 18 may he alined with the bolts or the like 19, permitting disconneclion of said links from the bolts and consequently permitting, the entire cover to be removed.

T he construction above described, permits movement of the cover 9 from its normal horizontal position, inwardly and downwardly, until it occupies a substantially vertical position at the inner side of the Wall 8, in which position it is suspended by the links 17. as seen in Fig. 4. In order to permit easy movement of the cover to this position or return to its normal position, it is preferably provided with appropriate knobs 20.

On account of the existing advantages for the details disclosed, they are preferably followed. However, within the scope of the 'nvent-ion as claimed, variations may be made.

I claim 1. A ventilator con'iprising a body having an inner wall to span the lower portion or a window frame, and end members at the ends of said wall for connection with the frame sides: a cover resting on said body, links at the outer sides of said end members extending across the innermost upper corner portions thereofuneans pivoting'the upper ends of said links to the ends of said cover, the lower portions of said links being provided with long itudinal slots having lateral throats opening through one edge of the links and studs projecting outwardly from said end members a nd received in said slots, said links permitting); movement of the cover from a horizontal to a vertical position, said throats permitting disconnection of the links from said studs when the links are moved to aline said throats and studs.

2. A ventilator comprising a body having an inner wall to span the lower portion of a *indow frame and end members at the ems of said well for connection with the frame sides; a cover resting on sa d body. said cover comprising a sheet metal plate, a downw ardly extending flange on the inner edef-e of said cover plate to engage the inner sidc of soil inner wall of the body. meal bars -tlli upon and ex ending across the ends of cover plate. ears formed on and projecting" upwardly from said bars, outwardly inclined said links at the outer sides of said end members and extending across the innermost corner portions thereof, said links having their upper ends pivotally connected with said ears, and provided in their lower portions with longritmlinal slotsv having; lateral throats opening; through one edge of the links, and headed studs projccting outwardly from said end members and received in said slo-s, said links permitt on movement of the cover from vertical position, said 'onnocflon of the links "(is when the links arc moved to i 'l throats and st the heads of too studs preventing inward springing or lateial disengagement of th links from the studs.
